During the NextMed 2014 event, I presented the first work done around cryoablation simulation. The presentation was entitled “Interactive Simulation for Cryotherapy Planning”.
In this talk, I presented a new planning framework for cryotherapy, compatible with the requirements set by interventional radiologists. Using contact-less technology, virtual cryoprobes can be interactively positioned in a sterile environment. Based on a fast yet accurate GPU implementation, the resulting iceball is computed in less that 30 seconds, outperforming previous work. This framework therefore allows to significantly decrease the safety margin by taking into account the synergistic effect of multi-cryoprobes with computation times consistent with clinical application while preserving accuracy. In this context, our numerical strategies, such as the choice of GPU computing or grid-based finite element approach, prove to be relevant.
